To all whom it may concern: I I with each other at theirinner end. Asshown Be itknown that I, JASON O. LOTTERHAND, in Fig. 3, each halfconsists of a rock-shaft a citizen of the United States, residing in the174, mounted near the opposite ends of its city of New York, county ofNew York, and straight horizontal *portion in bearings 175 StateofNewYork,haveinvented certain new upon the framework-above theplaten-roll and usefulImprovementsin TypeJVi-iters, of and having itsinner end .176 bent at an anwhich the followingis adescription,reference gle of about forty-five degrees to its straight being had tothe accompanying drawings, horizontal portion.

It results fromthis construcacross the machine through the guide-loops tion thatwhenever a type-key is depressed 4-3 of the vibrating -ribbon-throw,-bywhich the and the bail 151 thereby rocked thelinks180 ribbon is swung toand from the printingwill pull forward'upon the upper ends of'the line.The ribbon-throw is composed of two crank-arms 181and rock theshafts'174 in a like halves located on opposite sides of the directionto carry the ribbonover the machine beneath the ribbon-spools and eX-printing-point, and when the operatedkeyis' 5o tending inward therefrom,but not connected released and the bail 151 returned to normal 10position by the spring 153 the ribbon-throw will be swung forward andthe ribbon withdrawn from the printing-point. The arrangement of theribbon and the character of the ribbon-throw described obviate thenecessity for any sharp turns in the path of the ribbon, and therebyreduce the friction and wear upon its edges to the minimum,whileaffording an easy swinging movement of the ribbon to and from theprinting-line.

Each of the ribbon-spools 172 has secured to its forward side by studs1S2, Figs. 7 and 8, a ratchet-toothed ring 183, against whose smoothinner edge rests and travels a frictionroller 184,carried by the upperend of a springpressed arm 185, whose purpose is to afford sufiicientresistance to the turning of the ribbon-spools to preserve the propertension upon the ribbon. Engaging the outer side of the ratchet 183 is aspring-pressed actuating-pawl 186, pivoted at its lower end to averticallyreciprocating slide 187, guided near its lower end in a slotin a horizontal plate 188, Fig. 5, and provided near its middle with arightangular bend and at its upper end with a vertical slot, throughwhich passes a screw 189, entering the framework and serving to guidethe upper end of the slide 187, Figs. 7 and 8. A spring-pressedretaining-pawl 190, pivotally supported at its inner end, engages thetop of the ratchet 183 to prevent backward movement of the ratchet andspool while the pawl is engaged with the ratchet and at its outer end isbent to overlie the upper end of the vertically-reciprocating slide 187.

As will he understood from the foregoing description,when the slide 187is reciprocated, with the parts in the position shown in Fig. 7, thepawl 186 will turn the ratchet 183 and spool 171 step by step and drawthe ribbon across the machine from the spool 172 and wind it upon thespool 171, the pawls 186 and 190 which cooperate with the ratchet of theopposite ribbon-spool 172 being at such time disengaged from saidratchet, as presently explained. As shown in Fig. 7, the upper end ofthe pawl 186 is inclinedor beveled in such a way that when the slide1.87 is lifted to its extreme limit of movementthe contact of thebeveled upper end of the pawl with the screw 189 will force the pawloutward and disengageits tooth from the ratchet, as shown in Fig. 8, andthe upper end of the slide will at such timelikewise lift the outer endof the pawl 190 and disengage its tooth from the ratchet. By lifting theslide 187 to and maintaining it in this position, therefore, both pawlswill be held out of engagement with the ratchet and the spool be leftfree to be turned backward to unwind the ribbon therefrom. Now theactuating devices above described are exactly alike for both of theribbon-spools, and means is provided for constantly maintaining one orthe other of the slides 187 in elevated position, with the pawlsdisengaged from the ratchet of the correright-hand spool in Fig. 2 andas shown of the left-hand spool in Fig. 8, while the opposite slide 187is held in its lower and operative position, as in the case of theleft-hand spool in Figs. 2 and 7. To this end each slide 187 is providedupon its forward side with a stud 191, which studs cooperate with levers192 and 193 at the opposite sides of the machine, Figs. 4 and 5. Theforward ends of these levers 192 193 are loosely connected to therearWardly-bent opposite ends of acurved lever 19-t, fulcrnmed at itsmiddle upon a plate 195, secured to and depending from the forward sideof the top plate of the framework, Figs. 5 and 6. WVhen the lever 194 isrocked upon its fulcrum so as to throw its right-hand end downward, asin Fig. 6, the front end of the lever 192 will be carried downward withit and the rear end of said lever 192 will lift the slide 187,associated with the ribbon-spool 171 at the right side of the machine,as shown in Fig. 5, and the pawls cooperating with the ratchet of suchspool will be held out of engagement with said ratchet and the spoolleft free to be turned backward, while the opposite or left-hand end ofthe lever 191, being in elevated position, will hold the front end ofthe lever 193 elevated and its rear end depressed, as in Fig. 4, so thatthe slide 187 at the opposite side of the machine will be left in itslower and operative position.

For the purpose of reversing the position of the levers 192 and 193 tochange the direction of movement of the ribbon I journal a shortrock-shaft 195 in the right-hand side plate of the machine, Fig. 5, andsecure to its outer end a suitable crank or handle 196, Fig. 6, by whichit may be rocked backward and forward, and to its inner end a plate 197,provided with a slot eccentric tothe shaft 195 and engaging a stud 198upon the lever 192. By turning the rock-shaft 195 rearward-until thestud 198 upon the lever 192 engages the opposite end of the slot in theplate 197 the forward end of the lever 192 will be thrown upward and itsrear end downward, thereby releasing the slide 187 and at the same timerocking the lever 194 and causing its lefthand end to depress the frontend of the lever 193, Fig. 4, and lift the slide 187 shown in thatfigure to elevated position and disengage the pawls from the ratchet ofthe lefthand ribbon-spool. A coiled spring 199, secured at its lower endto an inwardly-projecting stud upon the side frame of the machine and atits upper end to astud upon the plate 197 at the middle of its upperedge, serves to hold the plate 197, and consequently the levers operatedby said plate, in their opposite positions.

The slides 187 are reciprocated to turn their rear ends of a pair ofside arms 47, pivoted to the side frames of the machine at their, front.ends at 48.

One of said side arms 47 hasin. the present instance a dependingextension at its front end, to which is con nected,

a coiled spring 51, which serves to yieldingly hold the universal rod 46in its normal position, Figs. 4 and 5-, and return it thereto afterhaving been depressed by a. type-key. The levers 200 and 201 areprovided atv their rear ends with in \vardly-projeeti ng studs 202, 5

which underlie the lower ends of the slides 187 at the opposite sides ofthe machine, and whenthese levers are rocked and their rear ends thrownupward at each operation of the machine by the depression of theuniversal left-hand side of the machine will be reciprocated by thelever 201, Fig. 4, while the lever 200 at the right side of the machine,Fig. 5, will play idly up and down, since its cooperating slide 187 isheld in elevated position by the lever 192. In Fig. 2 the reverseadjustment of the parts is shown, the righthand slide in that figurebeing maintained in elevated position and the opposite slide being leftin operative position.

The springs 203, connected to the lower ends of the pawls 186, serve thedouble function of pressing said pawls into engagement with the ratchetsof the ribbon-spools and of yieldingly holding the slides 187 in andreturning them to their lower positions.

I do not claim herein any features shown and claimed in my application,Serial No. 43,599, filed January 17, 1901, and of which this is adivision, nor in my other divisional applications, Serial No. 57,797,filed April 27, 1901, and Serial No. 68,697, filed July 17, 1901.
